Tips for obtaining laparoscopic tools: Do a browser search with the terms: buy used laparoscopic tools. Or from the ebay "endoscopy & laparoscopy" category at https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2499334.m570.l1312&_nkw=endoscopy+%26+laparoscopy&_sacat=184518, separately search for "grasper" and "scissors" to find the tools for ~$50 each. From the main ebay website, the path is: business and industrial > healthcare, lab, and life science > medical equipment > endoscopy & laparoscopy. If you run into a medical equipment disclaimer, just go ahead and make the purchase.
